Little Falls's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Passaic County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Little Falls. Below that spec discussion sit 10 installers, their order set by Google rating, since Little Falls is outside this site's window license file. A high rating is worth a look, not a finished decision.

What zone 5A means for a Little Falls window
New York-Newark-Jersey City, NY-NJ runs a January average near 31°F and climbs to about 76°F by July, a swing that adds up to roughly 5,286 heating degree days most winters, with 975 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Little Falls, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Little Falls's specific load is what tells you whether beating that floor is worth the extra cost.
